Foodborne pathogens

What are the impacts of foodborne pathogens and how can we reduce them?

Foodborne pathogens such as norovirus, Campylobacter, Listeria, Salmonella and Shiga toxin-producing Escherichia coli (STEC) cause approximately 2.4 million cases of disease in the UK population and impose an annual cost to society equivalent to £9.1 billion every year.

The overarching aim of this Area of Research Interest (ARI) is to empower the FSA to make policy decisions about microbiological foodborne disease based on the best evidence available.

We also commission external research to develop and refine tools and approaches, for example the development or optimisation of diagnostic tests or quantitative models. Research requirements are identified via an internal programme steering group and are informed by issues raised by the Advisory Committee on the Microbiological Safety of Food and the FSA’s Foodborne Disease Policy Framework. Research outputs are used to inform risk assessments and technical advice, to inform policy decisions and to evaluate the performance of changes to policy.

Important
From 1 August 2024 we publish reports in this area of research interest (ARIs) on our dedicated FSA Research and Evidence platform.

 

Research projects related to the programme

Evaluating our guidance on cross contamination

This project evaluated cross-contamination guidance, published by the Agency in 2011, for industry and enforcement officers. It aimed to understand how the guidance had been received and used.

Trichinella in UK Wildlife

This project involved the collection of fox carcasses and other wildlife species from around the UK for Trichinella testing.

Modelling the foodborne transmission mechanisms for norovirus

This project has developed a system dynamics model of the norovirus transmission system to assess the relative importance of the different epidemiological transmission mechanisms. The model will be further developed by the FSA’s Operational Research Unit to help prioritise further research into norovirus and to model the potential impact of different interventions.

A systematic review of the survival of norovirus in foods and on food contact surfaces

A systematic review of the persistence and survival of human noroviruses (hNoVs) in foods and the environment was carried out to answer two questions: What are the hNoV persistence characteristics in food and the environment? How can these properties be altered by applying physical and/or chemical treatments to foods or food contact surfaces?

Evaluating the effectiveness of depuration in removing norovirus from oysters

The project assessed the effectiveness of depuration in reducing norovirus in oysters, exploring the potential for novel approaches to improve effectiveness. A literature review of available evidence provided the starting point for a laboratory project aiming to identify possible enzymatic treatments to optimise depuration and significantly reduce norovirus contamination.

A critical review of methods for distinguishing infectious and non-infectious norovirus

This review aimed to identify methods used to detect norovirus in food, the environment and in clinical samples. The study assessed the potential of these methods to distinguish infectious and non-infectious norovirus, focusing particularly on approaches capable of assessing whether the condition of the norovirus capsid or RNA can be used as a guide to the likelihood of the virus infecting people.

Systematic and critical review on the potential use of bacteriophages on foods

This project aimed to assess the available information on the current and potential uses of viruses (bacteriophages) in food production to reduce the level of microbiological contamination (e.g. food pathogens or spoilage organisms) thus increasing consumer protection and/or increasing the shelf life of food.
